TSW1400EVM: signal sampling and reading by computer

Wojciech Baran
Prodigy 10 points

Part Number: TSW1400EVM

Hi

In my research project, I want to use the kit:
- TSW1400EVM
- ADS54T01EVM

I don't know if this is the right set. Maybe you can advise me?

The set is to be connected to a PC with Windows or Linux (USB + digital logic signal).

The whole thing is to accomplish the task:
- the computer issues the ENABLE signal (logic signal).
(The TSW1400 module starts saving samples in the memory. As long as ENABLE = 1 the set records subsequent samples in the memory. End of recording when ENABLE = 0 or MEMORY is full.
- after switching ENABLE to LOW the computer downloads the read data via USB
- and this is the end of the cycle, everything starts all over again.

- the computer issues the signal ENABLE = 1 .... again and the cycle repeats.
For each data logging cycle, the memory should "erase" and the recording is performed again.

My questions:
- will it fulfill my needs with this set?
- do I have to use TI software to support TSW1400 and ADS54 ...?
I would like to read the data with my own software. Does TexasInstruments provide a description and API documentation of the driver for these modules?
- what parameters the ENABLE signal must meet (what voltage level, steepness)
- where to connect the ENABLE signal to meet my needs? - to the ADS board or to the TSW?

regards
Wojtek

    Yes the ADS54T01 plus the TSW1400 is the proper combination.  This hardware combination in combination with HSDC Pro software will do almost everything that you want to do.

    You can download the HSDC Pro software from ti.com.  Once the software is launched, you can go to menu item Help > EVM GUI Help to access the software User's Guide.

    The hardware can be set up to arm the trigger/capture and then to wait for a trigger before initiating a capture.  Once the trigger is engaged, the TSW1400 will fill up it's memory with captured samples.  Then you can automate the data transfer from TSW1400 to your computer for post processing.  Once the capture is initiated, there is no way to stop it; it will capture per the memory depth established in the software.  For the next cycle, you can re-arm the trigger and wait for the next trigger to begin the next capture.

    Check out the User's Guide for HSDC Pro that discusses the details of the trigger function.  Check out the DLL User's Guide located in the software folder post install (C:\Program Files (x86)\Texas Instruments\High Speed Data Converter Pro\HSDCPro Automation DLL\) for information on automating software control and data transfer.
